An axial rod position determination system is described for a control rod in a nuclear reactor core, said system comprising: fixed incore detectors; analytical, on-line signature means for periodically creating a response signature database of expected detector response deviations for assumed rod positions from a reference detector response produced at the current rod position by said fixed incore detectors; and rod position determination means for continuously determining a moved rod position of the control rod by scanning the signature database for a signature match between the expected detector response deviations and current detector response deviations produced by said fixed incore detectors with the control rod at the moved rod position.
